The Pros and Cons of Wind Energy

PROS

Clean and Renewable

The production of wind energy doesn’t cause air pollution nor does it release harmful chemicals. It is renewable because wind is free and occurs naturally. Unlike coal or oil, wind can’t be drained. If a wind farm is placed in a windy area, the power supply is endless.

Growth and Potential

The department of energy reports a 30% annual growth in wind energy production. The various sizes of wind turbines leave the potential for both residential and commercial use of wind power. This allows wind energy to grow at a much faster rate due to its versatility.

CONS

The threat to wildlife/environmental impact

Wind turbines can be a threat to birds and other wildlife in the air. This can be dangerous during the first few years after the turbines have been built. It usually takes wildlife a while to get used to having the rotating blades on their terrain. About 440,000 aviary animals are killed or injured by turbines each year[1].

Additionally, wind turbines require large open spaces. Usually, some tree cutting is required. The deforestation process can have a negative impact on the ecosystem of the area.

Noise Pollution

Wind turbines produce high levels of noise pollution. The mechanical sounds produced from the turbines can be loud and obnoxious. The spinning blades also create a wind vortex that makes the wind louder.

Location limitation

Wind farms only work best in locations with high winds. These are usually remote areas. As result transmission lines are required in order to power a city with the turbines being far away outside of the city where there is more room.
